There is a varying chance for R1-R2 (Minor-Moderate) events, and a slight chance for R3 or greater events. No proton events are expected at geosynchronous orbit, barring significant flare activity. The greater than 2 MeV electron flux at geosynchronous orbit is likely to reach high levels on 18-19 and 23 Feb, and 10-15 Mar. Normal to moderate levels are likely to prevail throughout the remainder of the period. Geomagnetic field activity is likely to reach G1 (Minor) levels on 28 Feb, 09 and 12-14 Mar, with active levels likely on 17-18 Feb, and on 01 and 15 Mar, due primarily to CH HSS influences. Quiet and quiet to unsettled conditions are expected to prevail throughout the remainder of the period.
